B and shoulder "at -the upper ond to receive the knob,.the upper end beini@r riveted over` at BX as shown in this tit ue to hold the knob to the body. body A is formed with a square J on its exterior adapted to lit a corresponding:Y square in 'a socket K on `the head of a box Spanner L.

Referring to other method ot securingthe rotatable knob or dise B upon the' upper end of the body A, a recess Bis `formed in the centre of thev knob B adapted to receive the upper end of the body A, and a groove B2 is formed in the neck of the body in which is secured a grub screw B3, the point ot which tits the groove, thus securing the knob B rotatively4 to the body A.

It will be clear that the apparatus shown is applicable to other implements or tools ot this kind required to be rotated by hand and retained upon the work.

ln either oase the knob or disc B is held in the palm of the hand and the milledring F may be gripped between the tiret finger and the thumb and rotated While retained in position in the hand, 'thereby rotating the main portion of the tool, and simultaneously the tool may be retained upon the work Whether the slot ot a screw or a nut or the* like, thus enabling by this tool the whole operation ot the turning the screw or the nut or the like to be 'effected by one hand. Alternatively in larger tools it bothfl'iand's are employed, the one may hold the rotatable knobj While the other grips the milled ring or the like', and the tool may be retained in Contact with the Work Without any necessity to remove the tool therefrom.
